[petsc-users] cmake METIS problem

[Tim Gallagher]

You can set the CXX environment variable, CMake should always pick those up.

I do specify --with-cc --with-cxx --with-fc. Here is the configure options 
configure --known-level1-dcache-size=32768 --known-level1-dcache-linesize=32 --known-level1-dcache-assoc=2 --known-memcmp-ok=1 --known-endian=big --known-sizeof-char=1 --known-sizeof-void-p=8 --known-sizeof-short=2 --known-sizeof-int=4 --known-sizeof-long=8 --known-sizeof-long-long=8 --known-sizeof-float=4 --known-sizeof-double=8 --known-sizeof-size_t=8 --known-bits-per-byte=8 --known-sizeof-MPI_Comm=4 --known-sizeof-MPI_Fint=4 --known-mpi-long-double=1 --download-f-blas-lapack=1 --download-mumps=1 --download-blacs=1 --download-metis=1 --download-parmetis=1 --download-scalapack=1 --download-superlu=1 --download-superlu_dist=1 --with-c2html=0 --with-debugging=0 --with-clanguage=cxx --with-cc="mpcc_r" --with-fc="mpxlf_r" --with-cxx="mpCC_r" --CFLAGS="-q64 -O3 -qmaxmem=-1 -qstrict -qarch=auto -qtune=auto" --CXXFLAGS="-q64 -O3 -qmaxmem=-1 -qipa -qstrict -qarch=auto -qtune=auto" --FFLAGS="-q64 -O3 -qmaxmem=-1 -qarch=auto -qtune=auto" --with-sowing=0 --with-batch=1 --with-shared-libraries=1 --known-mpi-shared-libraries=1 --with-x=0 --with-pic=1 

But cmake does not use given cxx. You see, cc="mpcc_r" is passed to cmake, but no cxx. 
Cmake tries to find cxx but failed.

Hi, 
I try to install petsc-dev on AIX/PPC cluster. 
I'd like to use xlc, however, there is a dead gcc/g++ installed in /usr/bin. 
Since I am not the administrator, I can't do anything to remove/update it. 





Specify the compilers using --with-cc --with-cxx --with-fc. I suggest you specify the MPI 
compiler wrappers for this machine.

The cmake configure file for metis tries to find c++ compiler, and reported error with that g++.

I think the testing for c++ compiler can be removed here?
